- Page 3 Prophi ® Section1 General The dynamic power factor controller Prophi-6T represents the consequent development of the Prophi-series with new innovative ideas and a multitude of functions. It has been especially designed to control thyristor modules for dynamic switching of power capacitors for power factor correction (for example TSM-LC or similar). By using a very fast type of processor, it has been possible to obtain extreme short switching cycles which allows the usage for dynamic power factor correction.

- Page 5 Prophi ® Section 2 Installation and connection of the controller The device is designed to be incorporated into the front panel of a PFC-cabinet. It requires a switchboard section of 138 x 138 mm to DIN 43700/ IEC 61554. The controller is inserted from the front and is attached by means of the appended clamps.
- Page 6 Prophi ® 2.1 Current measurement When installing the current converter, care should be taken to ensure that the load current flows through it. The outputs of the compensation network must be installed behind the current converter (in the direction of current flow). If the device is connected up via sum-current converters, the overall conversion ratio is entered.
- Page 7 Prophi ® 2.3 Alarm output / error messages The alarm contact is closed in normal operation and opens in the event of a fault. The relevant fault is simultaneously shown on the display in plain text (alternating with the standard display in automatic operation). The following fault messages are displayed: UNDER-COMPENSATED Display and relay output missing reactive power...
- Page 8 Prophi ® Section 4 Automatic operation - display of network parameter The controller is set to automatic operation as standard. Capacitor stages are then automatically connected in or out in order to reach the target power factor. This happens when the required reactive power exceeds the value of the smallest capacitor stage. In automatic operation, various network parameters can be displayed by repeatedly pressing the "ENTER”...
- Page 9 Prophi ® Section 5 Programming Pressing the "Operating mode” key once takes the user from automatic operation to Programming mode. The upper display always shows the parameter and the lower one the set value. The values are changed by pressing the é / ê keys. Subsequent pressing of the "ENTER” key stores the value and takes the user to the next parameter.
- Page 10 Prophi ® 6 POWER 1. STAGE: [ 0.01 ... 255.99 ] kvar To determine the controller's response sensitivity, the dimensions of the network's smallest capacitor (stage 1) must be known. They are entered in two steps in kvar. The integral kvar values (before the comma) are initially selected via the é / ê keys and saved with ENTER.
- Page 11 Prophi ® 11 DISCONNECTING TIME [ 20 ... 1000]ms This refers to the time between disconnecting the capacitors to reduce the momentary network capacitance.. Default setting: 1000 ms Selection is performed via the é /ê keys. Continue with ENTER 12 DISCHARGE TIME [ 20 ...1000]ms This is the time for which an individual output is blocked between connecting and disconnecting.

The starting condition is STOPP (no stages connected). Connections are made by pressing the é...
- Page 13 Prophi ® Section 7 Service menu The service menu is reached by the operating-mode key. The stored maximum values of the network parameters can be displayed here. In addition, a fault memory is available, in which the last 40 fault states of the system are stored with fault code and in plain text.

- Page 15 Prophi ® Section 9 Control principle The control response of the Prophi-6T can be selected in programming mode. In principle, the controller has four different control modes: 1. Sequential connection In sequential connection, the required capacitor stages are successively connected and disconnected in stages (last in - first out).
- Page 16 Prophi ® Section 10 Initial operation The controller must have been installed before being set up and operated. All network-specific parameters are fully programmed as described in section 5 (Programming) by being entered in sequence and stored. The controller is then set to automatic operation with the operating mode key.
